Write a report that presents code and results that evaluates the
below hypotheses related to African Elephant weight. The data file is
elephant.study.csv. There are three columns, where each row
is an individual sampled elephant, indicating the variables of
weight (weight in lbs), age.years (age of
elephant in years), and lat (mean latitude of the elephants
home range).
grateful.Throughout, add text around your code and results to allow the reader to follow your thinking. The text however should be minimal and to the point.
I hypothesize that adult African Elephants (Loxodonta africana) increase in weight as they age because they are more efficient at conserving energy and acquiring high quality resources. As such, I predict that older elephants will weigh more than younger adult elephants. Further, I hypothesize that there is a latitudinal effect on the weight of elephants across the continent of Africa because of the extreme drought in the southern part of their range. I predict that elephants further north will weigh more than elephants further south.
I evaluated these hypotheses by aggregating data on weights of elephants from collaborators. Each individual elephant was weighed in the same manner while being fit with a GPS collar. Each individual had a known age due to longterm demographic monitoring. I derived the mean latitude of each elephants dry season home range.
